To all whom it may concern: f Be it known that LHE'RBERT L. HILDRETH, a.citizen of the United States, residing at Boston, in. the county ofSuffolk and State of Massachusetts, have invented certain new and usefulImprovements in Candy-Pulling Machines, of which the following is Iaspecification. r

My vention relates tothe manufacture of candy, and more particularly tocandy- Its object is to provide a machine be driven by any suitablemotor candy equal to the best that has heretofore been obtained when thecandy was pulled by hand.

Attempts have heretofore been made to work` candy in a manner analogousto that in which dough and other substances are treatedf-that is to say,to place the mass within a chamber into which moving arms project. Anexample of this -construction is shown in'. United States Let tersPatentlNo. 511,011, granted December 19, 1893, to P. J G. Firchau. Insuch ma' chines the mass of candy is supported in whole or inpart byachamber, and the function of the moving arms or projections is toalternately mass and stretch the material, as

b Thismethod of treatment and-the machines which embody it arenotsuccessful or practical to produce the results heretofore obtained byhand-pulling,

which results must be obtained in any successful candy-pulling machine.

My invention includes 'a pulling member or candy-puller, a plurality ofwhat may be called supports for the candy or candy- I hooks to which thebatch of candy to be pulled is attached, and means 'for produ ting arelative infand-'out motion Aof thesegparts,

. to be hereinafter more fully described, wherethe candy is alternatelypulled intohanks or strands and the hanks or strands Iso prorealized bymoving ,ducedf are reunited. f

y The .relative in-and-out motion of the .candy-puller and thecandy-hooks may be either the candy-puller or the candy-hooks, or both,and the mechanical devices by which Athis relative motion isaccomplished are not essential to the invention.

. -As an illustration of the principles of my c invention a specificembodiment thereof-is ,'5-5.

shown inthe drawingswhich accompany and vformV apart .ofthisspecification. Inthis'p articular form of the apparatus two mandy-hooks`are employed, and both the candy-puller and the candy-hooks are causedtomove, therebybut no such joint motion is an essenthe -invention being aplurality 'of candyhooks, a candyfpuller, and mean'sof producingvarelative mand-out motion of. these parts.V Figures 1 and 2 are drawingsshowing a specific form of candy-pulling mechanism embodying myinvention. Fig. 3 is a diagram illustrative of the infand-out motion ofthe candyuller relative to the candy-hooks. Y

Fig. 4 is a diagram illustrative of the in-andout motion of.thecandy-hooks relative to the candyepuller.

InFig'. 1, bei' or candyuller. It is rigidly attached to a horizontashaft or trunnion S, supported *in the bearings B, and is free tooscillate about the axis .of shaft S in the plane of the paper. to thecandy-puller A by .the rotation of a horizontal shaft S4 through theintermediary of the doubleycrank C and connecting-rod R. In itsreciprocating motion the candy puller .A oscillates between theindicated by dotted lines at A and A. At its lower extremity thecandy-puller preferably carries a Iiange or foot F, which serves toprevent the candy from slipping down.v

H and H are candy-hooks mounted upon 'the extremities of thehorizontalqwalkingf '75 A is the movable pulling mem5' A reciprocatingmotion is imparted two positions beam K, whichis centrally and rigidlyat- IOO 'The

T is a table or platiibrm interposed between 'the candy-pullingmechanism and the driving-gear below. A

F ig.. 2 is a. plan view of the table T and candyf-hooks, showing alsotheshaft Sand the two cranks'C and 0., In this figure, d

and d' are two slots cut in the platform T to permit of thereciprocatory motion of the two candy-hooks H and H'. tion of' themechanism these oseillate between the positions H1 and IL',respectively.

In the operacandy-hooks H and H' and In using the mechanism to pullcandy the' vin the interval during which the candy-puller has moved fromthe position shownat A to the position shown at A' the candy-hook H' hasmoved from its initial position to its central'position 2, Fig. 2, andthe two hanks are reunited. On the return stroke of the candypuller fromthe position shown at A' to the position shown at A the candy-hook H'moves from the position 2 to the position shown at H1', and the reunitedstrands are maintained at substantially the same length. AThecandy-puller next passes to the position shown vat A" and back toA,executing the same motions relative to the hook H a's have just beendescribed relative to the hook H', and this cycle is repeated,alternately pulling the candy into two strands and reuniting the strandsas pulled. R

Careful consideration will show that the relative motion of the pullerto the candyhooks, if the candy-hooks be regarded as stak tionary, isthat shown diagrammatically in Fig. '3, in which, as in Figs. l and 2, Hand H' indicate the candy-hooks and the dotted curved line in the shapeof a figure 8 is the locus of the candy-puller relative to thecandy-hooks. It is easily seen, therefore, that in the device describedthe candy-hooks need not be movable, but may be fixed to the platform,and that the candy-puller may have imparted to it two reciprocatingmotions' at quadrature with each other without chang-- in the-resultsobtained. Similarly by de- Ve oping the motion of the candy-hooks relative to the candy-puller a suitable motion of the candy-hooks is found,which'if imparted to the' candy-hooks while keeping the candypullerfixed will not alter the function of the machine. i

Fig. 4 illustrates diagrammatically the motion which may be imparted tothe candyhooks `whilel keeping the candyepuller staf tionary in' orderto realize the hereinbeforedescribed inand-out motion of the candyhooks'relative'to the candy-puller. In this figure the circles shown indotted lines indicate the loci of the candy-hooks H and H', a completecycle during the operation of the michine being divided into eightlequal interva s.

which latter phase they are lagain in the same line and about to repeatthe cycle shown. In this diagram, moreover, the hanks or strands ofcandy are indicated by a dotted line or lines in such a manner as toillustrate the pulling of the candy.

Careful consideration of myV invention as herein set forth will showthat in practising it the mass of candy is notinclosed or supe` portedwithin a chamberA or receptacle, nor is it alternately stretched andmassed. On the .other hand, the candy is supported at all times duringthe pulling operation solely by means of the devices which I havehereinbefore spoken of as the candyhooks" or'the "candy-puller, whilethe motions of these devices in the manner described operate to eX- tendor stretch thecandy and to produce 4 lapping or reuniting of the pulledstrands or hunks into position to be pulled or stretched again, but atthe same time without massing the candy.

An examination of Fig. 4 in particular will show that by means of' myinvention there is no alternate massing and stretching, asin the priorart, out a stretching and lapping, as before explained.

It is to be noticed that in any machine em'- l bodying the inventionhereinbefore set forth the question of whether or not the members whichtake part in the ulling operation should be more accurate y designatedas supporting members or as pulling" mein- IDO bers may depend in wholeor in part upon A A the manner of their disposition with reference tothe effect of gravity upon'the candy during the Apulling operation. inthe apparatus of Fig. 1 th'e parts or members H H' have adouble-function-that is, that being disposed horizontally they tend tosupport the candy which is ,connected to them against gravity and alsoserve to hold the ends of' the candy batch against the pull of the partA. Hence the application of the eX ression pulling member or "candypuler to the part A is not to be taken as indicating that the parts H H',to which the term support" is applied, may not also take vpart inthepulling operation. In the embodiment of my invention shown diagrammatidally in Fig. 3, in which the s'o-called supports HH' are stationary andthe "puller, so called, moves around andbetween H H', it is obvious thatthefunc'tion of' supporting and pulling lthe candy may be shared bythese'parts in' a manner dependent upon the planes in which theymay bedisposed with reference to gravl ity. The same is true'of Fig. 4,wherein the two members above-'spoken of as candy` supports" are shownas moving circidarly For example,
